For example, as shown in FIG. 2c, the UE may send the cell type support capability information of the terminal to the base station (for example, an eNB) in an attach request, and send the information to the core network element (for example, MME) via the base station. The core network element may save the cell type support capability information of the terminal in the context information of the corresponding terminal in the authentication and security verification (authentication/secutity) process.

Alternatively, the UE may also carry the cell type support capability information of the terminal in the Radio Resource Control (RRC) message to carry the cell type support capability information of the terminal to the base station by using the RRC message, and then notify the core network element by the base station. . The RRC message may be, for example, an RRC connection setup complete message, or an RRC connection reconfiguration complete message.

The cell corresponding to the cell type information or the cell corresponding to the cell identifier determined according to the cell type information supported by the terminal sends a paging message instead of sending a paging message to all the included cells, which can reduce the sending amount of the paging message. Reduce system energy overhead.

3 is a schematic flowchart of another embodiment of a paging method according to the present invention. In this embodiment, a paging message sent by an MME to an eNB carries information about a cell type supported by a UE. This embodiment includes:

31: The MME acquires cell type information supported by each UE registered thereto.

After the UE is powered on, it can be registered to the MME through an attach procedure. In this process, the UE reports the capability information of the UE to the MME. Alternatively, the MME may also obtain capability information of the UE from a Home Subscriber Server (HSS). The capability information of the UE may carry the cell type information supported by the UE.

The MME may store the UE identifier corresponding to the context information of the UE, and the context information of the UE may store the cell type information supported by the UE.

The cell type information supported by the UE in this embodiment may be a specific type of the cell type, for example, type 1, type 2, ..., where type 1 may be specifically a new type of cell, such as an NCT cell, and type 2 may be a traditional type. Community.

The cell type information supported by the UE in this embodiment may also be a cell type support capability information index of the terminal, for example, 1, 2, where 1 may represent a new type of cell, 2 denote a legacy type cell, or a frequency band information of a cell type.

32: After receiving the downlink data notification message, the MME obtains cell type information supported by the UE to be paged.

The downlink data notification message carries the bearer ID of the Evolved Packet System (EPS), or carries the identifier of the UE. The MME may determine the context information of the UE to be paged according to the EPS Bearer ID or the UE identifier. The information of the cell type supported by the UE is found in the context information. In this case, the MME obtains the cell type in the paging message. The MME obtains the cell type supported by the UE. For example, the MME obtains the cell type supported by the UE. It is also the cell type supported by the UE. Or,

Alternatively, the downlink data notification message carries an EPS Bearer ID or a UE identifier, and the MME The context information of the UE to be paged may be determined according to the EPS Bearer ID or the UE identifier, and the cell type information supported by the UE is found from the context information. In addition, the MME also pre-configures the correspondence between the information of the cell type and the other information, and the manner of the cell type that is finally acquired by the MME is different from that of the UE, for example, the cell type supported by the UE is reported by the UE. And obtaining, according to the correspondence between the pre-configured cell type and the cell type support capability information index of the terminal, the cell type support capability information index of the UE, and then carrying the cell type support capability information index of the UE in the paging message.

33: The MME sends a paging message to the eNB, where the paging message carries the cell type information supported by the UE.

34: The eNB sends a paging message only to the cell corresponding to the cell type information supported by the UE.

For example, the cell served by the eNB includes cell 1, cell 2, and cell 3, and the type of cell 1 is type 1, the type of cell 2 is type 2, and the type of cell 3 is type 3. The correspondence between the cell identifier of the cell served by the eNB and the cell type may be configured at the time of planning.

Assuming that the paging message sent by the MME carries Type 1 and Type 2, the eNB may send a paging message only in Cell 1 and Cell 2 without transmitting a paging message in Cell 3.

Optionally, the information about the cell type corresponding to the pre-configured cell identifier in the eNB is consistent with the information of the received cell type. In this case, the corresponding cell may be directly determined according to the correspondence, for example, pre-configured in the eNB. The corresponding relationship may be a corresponding relationship between the cell type and the cell identifier. In this case, when the information received by the eNB is a cell type supported by the UE, such as type 1, type 2, etc., the corresponding cell may be directly determined according to the corresponding relationship, Sending a paging message to the corresponding cell. Or,

The cell type information corresponding to the pre-configured cell identifier in the eNB may be inconsistent with the received cell type information. In this case, the eNB needs to configure a cell type information in addition to the correspondence between the cell identifier and a cell type information. Correspondence with another cell type information. For example, the corresponding relationship between the cell type and the cell identifier is configured in the eNB, and the correspondence between the cell type and the cell type support capability information index is configured, and the paging cell received by the eNB carries the cell type support capability information index, according to the index. And the two corresponding relationships may determine the corresponding cell, and only send the paging message to the corresponding cell.

In this embodiment, the cell class supported by the UE is carried in the paging message sent by the MME to the eNB. The type information may be such that the eNB sends a paging message only to the cell corresponding to the cell type information supported by the UE, so as to reduce system energy overhead.

4 is a schematic flowchart of another embodiment of a paging method according to the present invention. In this embodiment, an eNB sends a message to an MME, so that the MME sends a paging message to a specific eNB instead of sending a paging message to all connected eNBs. Examples include:

41: Each eNB connected to the MME sends a message to the MME, where the first message carries cell configuration information of the eNB, and the cell configuration information is cell type information supported by the eNB.

The first message may be an existing message or a new message.

The existing message is, for example, a setup request (SI SETUP REQUEST) message. In this case, the MME may also send a setup response (SI SETUP RESPONSE) message to the eNB; or configure an update (ENB CONFIGURATION UPDATE) message, in this case, The MME may also send a configuration update response (ENB CONFIGURATION UPDATE ACKNOWLEDGE) message to the eNB.

After receiving the first message sent by the eNB, the MME may store the cell type information supported by the eNB. The specific representation manner of the cell type information supported by the eNB may also be a cell type supported by the eNB, such as type 1, type 2, or... or a cell type support capability information index supported by the eNB, such as 1, 2 ... , or the frequency band information of the cell type.

42: The MME acquires cell type information supported by each UE registered thereto.

43: After receiving the downlink data notification message, the MME obtains the

The MME determines the first eNB, and sends a paging message to the first eNB, where the paging message carries the cell type information supported by the UE or the intersection of the cell type information supported by the first eNB and the cell type information supported by the UE. The first eNB refers to an eNB in which the supported cell type information and the cell type information supported by the UE intersect.

For example, when it is determined that the cell type supported by the base station and the cell type supported by the terminal have an intersection, the paging message is sent to the base station according to the cell type information supported by the terminal. For example, the supported cell types reported by the eNB1 are type 1 and type 2, the supported cell type reported by the eNB2 is type 4, and the cell types supported by the UE are type 1, type 2, and type 3, then the cell type supported by the eNB2 is The cell type supported by the UE does not have an intersection, so the first The eNB only refers to eNB 1 instead of eNB2, that is, the MME only sends a paging message to eNB 1, and does not send a paging message to eNB2.

In addition, the information that can be carried in the paging message sent to the first eNB is type 1, type 2, and type 3 (that is, cell type information supported by the UE), or may be type 1 and type 2 (that is, The intersection of the cell type information supported by the first eNB and the cell type information supported by the UE

45: The first eNB sends a paging message only to the cell corresponding to the information carried in the received paging message.

For example, if the paging message carries Type 1, Type 2, and Type 3 (or carries Type 1 and Type 2), and the first eNB only supports Type 1 and Type 2, the first eNB only corresponds to Type 1 and Type 2 The cell sends a paging message. The correspondence between the type of the cell and the cell identifier may be configured at the time of planning.

Optionally, the first message reported by the eNB to the MME further carries a correspondence between the cell type information and the cell identifier, where the MME determines the cell type information supported by the UE (or the cell type information supported by the first eNB and the cell supported by the UE). After the intersection of the type information, the cell identifier corresponding to the cell type information supported by the UE is determined according to the corresponding relationship, and then the corresponding cell identifier is carried in the paging message sent by the MME to the first eNB, and the first eNB receives After the paging message, the paging message is sent only to the cell corresponding to the cell identifier.

Optionally, the MME may also configure a correspondence between the cell type information and the cell identifier, and then the process of determining the cell identity according to the corresponding relationship, and carrying the cell identifier in the paging message sent to the first eNB.

The MME of the present embodiment sends the paging message only to the eNB supporting the cell type supported by the UE, instead of sending the paging message to all the eNBs connected to the MME, which can further reduce the sending amount of the paging message and reduce the system energy overhead.

FIG. 5 is a schematic flowchart of another embodiment of a paging method according to the present invention, including:

51: Each eNB connected to the MME sends a message to the MME, where the message carries the cell configuration information of the eNB, where the cell configuration information is a cell identifier, a cell type, and a mode of active sleep transition of the cell. Correspondence of information.

That is, the eNB sends the cell identifier of each cell of the cell, the cell type of the cell, and the active sleep time information of the cell to the MME, so that the MME learns each eNB packet. The cell identity, cell type, and active dormancy of each cell included.

The first message may be an existing message or a new message.

Existing messages are, for example, SI SETUP REQUEST messages or ENB CONFIGURATION UPDATE messages.

After receiving the first message sent by the eNB, the MME may store information of the cell included in the eNB. For example, cell 1 corresponds to type 1 and activates sleep transition style information 1 , cell 2 corresponds to type 2, and sleep sleep pattern information 2 is activated.

52: The MME acquires cell type information supported by each UE registered thereto.

53: After receiving the downlink data notification message, the MME obtains the message

54: The MME determines the first eNB, and sends a paging message only to the first eNB, where the paging message carries the cell identifier of the first cell.

For example, if the type of active sleep transition indicates that the cell within the intersection is currently active, a paging message is sent to the base station.

The first eNB may be determined in the manner of the foregoing embodiment, where the first eNB is an eNB in which the supported cell type has an intersection with the cell type supported by the UE.

In addition, the paging message sent by the MME of the embodiment to the first eNB carries the cell identifier of the first cell, where the cell type is the same as the cell type supported by the UE and is currently in the same manner as the previous embodiment. The cell in the active state. For example, the MME can determine whether it is the same as the cell type supported by the UE according to the type of the cell reported by the eNB, and can determine whether the current state is active according to the style information of the active sleep transition of the cell.

55: The first eNB sends a paging message only to the cell corresponding to the cell identifier carried in the received paging message.

For example, the first eNB parses the cell identity from the received paging message, and then sends a paging message only to the cell corresponding to the cell identity (ie, the first cell).

The MME of this embodiment sends a paging message only to the eNB supporting the cell type supported by the UE, instead of sending the paging message to all the eNBs connected to the MME, which can further reduce the transmission amount of the paging message and reduce the system energy overhead. In addition, the eNB in this embodiment sends a paging message only to a cell that supports the cell type supported by the UE and is in an active state, so as to avoid sending a paging message to the cell. The waste caused by the dormant cell can further reduce the system energy overhead.

In addition, in the foregoing embodiments, in order to enable the eNB and the MME to interact normally, the representation manners of different cell type information may be pre-configured in the eNB and the MME, for example, a indicates type 1 and b indicates type 2 and the like. The configuration mode can be implemented in the Operation Administration and Maintenance (OAM) mode or in the hardening mode, that is, the third-party signaling interaction can be used to enable the eNB and the MME to know the representation of each cell type information, or to use the pre- The code configures a representation of each cell type information. Furthermore, various correspondences between the MME and/or the eNB configuration may also use the OAM configuration mode or the solid configuration mode.

By any of the above embodiments, the amount of paging messages sent can be reduced, and the system energy overhead can be reduced. On the other hand, since the NCT cell is dormant, when paging the UE of the cell in the dormant state, the response delay of the UE to the network paging is increased, and in severe cases, the paging failure occurs. In order to solve the problem of delay or failure of the paging response, the present invention also provides the following embodiments.

FIG. 6 is a schematic flowchart of another embodiment of a paging method according to the present invention, including:

61: The eNB sets the statistical duration T, and counts the arrival of the paging message of each cell served by the eNB within the duration.

The arrival status of the paging message may include: the number of paging messages that arrive when the cell is in an active state, and the number of paging messages that arrive when the cell is in a dormant state.

For example, the cell served by the eNB includes the cell 1 and the cell 2, and each cell has its own active dormancy conversion style information, such as activation from time t1, and the activation time is t2. Therefore, according to the active dormancy conversion style information, each cell can be learned. The cells are in a dormant state or an activated state in a corresponding time period within the statistical duration T. And, in the corresponding time period, the eNB may also count the number of paging messages that the cell arrives, for example, the cell 1 is in an active state in the time period of t1 to t1 + t2 of the statistical duration T, and the time is tl~tl+t2. The number of paging messages arriving in the cell 1 in the segment can determine the number of paging messages that arrive when the cell 1 is in the active state. A similar method can also determine the number of paging messages that arrive when cell 1 is in a dormant state, and the number of paging messages that arrive when cell 2 is in an active state and a dormant state, respectively.

62: The eNB determines whether the statistical result of each cell matches the currently activated sleep transition style information, and if not, performs 63, otherwise, performs 64.

The number of paging messages that arrive when the cell is in the dormant state, and the number of paging messages that arrive when the cell is in the dormant state, may be, for each cell, the number of paging messages that arrive when the cell is in the active state. When it is a small amount, it indicates a match, otherwise it does not match. The specific quantity or quantity may be two thresholds respectively, and the number of paging messages that arrive when the cell is in the active state is greater than the first threshold, and the number of paging messages that arrive when the cell is in the dormant state is smaller than the second. A threshold indicates a match, otherwise it does not match. Alternatively, a threshold may also be set. If the difference between the number of paging messages that arrive when the cell is in the active state and the number of paging messages that arrive when the cell is in the dormant state is greater than the threshold, it indicates a match, otherwise it does not match. . Alternatively, a threshold may also be set. If the ratio of the number of paging messages that arrive when the cell is in the active state to the number of paging messages that arrive when the cell is in the dormant state is greater than the threshold, it indicates a match, otherwise it does not match. The specific matching principle is not limited to the above, and other principles may be set.

63: The eNB adjusts the currently activated sleep transition style information of the unmatched cell, so that the adjusted active sleep transition style information matches the statistical result. You can then repeat step 61 and its subsequent steps.

For example, the activation start time and/or the activation duration of the unmatched cell are changed, so that the number of paging messages respectively counted according to the adjusted activation and sleep time periods satisfies the matching principle of the above setting.

64: The eNB keeps the current active sleep transition pattern unchanged. You can then repeat step 61 and its subsequent steps.

Optionally, the embodiment may be performed separately, or may be combined with the foregoing embodiment. For example, the eNB sends a paging message only to the cell corresponding to the type supported by the UE, and the eNB also counts the paging message of the NCT cell and adjusts the NCT cell. Activate sleep transition style information.

In this embodiment, by adjusting the active dormancy conversion style information of the cell, the style information can be matched with the arrival model of the paging message, thereby reducing the paging delay and the paging failure rate.
